lie it known that l, (tinnitus ii. DIENER, a eitiaen ot' the l nitedStates, residing at lhiliulelphia, in the eounty of Philadelphia aialState at leimsyh'ania, have invented eertain new amt useful improvementsin t'nrhureters, of which the following is a. speeilieation, retei'eneebeing lltttl to the ac- ,-ompan vin;, drawings.

This invention relates to improvements in earluireters, and has for itsprimary object to provirl'e a lleviee of this character adapted to bearranged in the exhaust pipe of an engine for heating, kerosene andother eom paratively heavy oils, whereby the expense in iilent to theoperation of the engine may he reduced to a minimum.

The inventi n has. for a more partieular object toproi'ide an improvedeonstruetion (if-the l'ieater body, and means fol-seeming the sameinthe'exhaust pipe, a earbareter .proper in eomn'innieation withthe gaspassage, of the heater, and oil and water supply pipes in eonnnunicationwith the oarhuret- '5 mg chamber and-extending through theheater hotlywhereby the same areheateil by the exhaust gasesfirom the engine.

'lhe invention has for another a,ml very important object ti'rprovide animproved "eonstrluition oi the carburetor proper, the same embodying agasolene reservoir to contain the initial fuel supply, means formounting said earhuretm' upon the exhaust; pipe and directing.heatotlairintothe ear bureting chamb r. a mixing valve opened by sueti'iih' uponthe intake stroke of the engine piston' whereby the air is (ii-awn intothe carbureting chamber. oil and water supply pipes, and a control valvetor regulating I the supply of oil and water through the earhuretiingehamber.

The invention has i'or still another object; t generally improve andsiiuplil') the oonstruetion ol' (leviees ol' the ab ve ehararter, toiuerease. their ellieieney ainl reliability in operation, and enable thesame to be pro- (ha-ed at comparatively small manutaeturing ('ost.

With the above :illtl other ohjeets in view 0 as will heroine apparentas the ll(?S(.l'll)tl()ll proeeeils, the invention eonsists in rei'tain.ronstruetions, eomhinatious, and ;ll:lll,l0-

ments of the parts that i shall hereinafter fully (iescril'ie and claim.1

l or a, full understaiuliug of the in\'en-' tion, reference is to be hadto the following are integrally eonneetetl by a tube 12,

description and accompanying drawings, in which 7 Figure 1 i.' avertical section through the earbureter showing the same ronneeted inthe exhaust pipe of a gas engine; Fig. 2 is a section taken on the lineof Fig. 1; Fig. 3 is a section taken on the line 33 of Fig. 1; Fig. i isa startion taken 011 the line 4 4 of Fig. 3; Fig. 5 15a seetion taken.on the line 5--:3 of Fig. 1: Fig. 6 is a sec- I .tion taken on the line(3(3' of Fig. 5; Fig. 7 is a top plan view of the liliXili;'(illtU1ll)8l'; Fig. 8 is a face view of the head of one of the needlevalves.

Referring in detail to the drawings 5 and t3 designate-two seetions ofthe exhaust pipe of a gas engine which extend at right angles withrespect to each other. One end of the horizontal seetion t) of this pipeis threaded for the eonneetion thereto of an elho\\'-joint member r.This member is formed upon its upper open end with a substantiallyannular outwardly projecting! flange H, thereby forming the upstainlingz; annular shoulder t The body of the heater or minor. unheated atlth'incliules an elongated intermediate portion 11. the opposed endwalls of which Below this tube the butlv 10 is contracted and formedwith a eireular outlet 13 for the we haust gases. The edge of thisoutlet is adapted to seat upon the annular flange. 9 of the elbow jointmember 7. The tube 12 is (centrally formed with a depending interiorlythreaileal boss 14 in whieh the upper threal etl eml ot' a bolt 15 isadapted to beengaged. 'lhisliolt' is inserted upwardly through anopening proiiilettin the bottoin wall of the elbow 7. as elearly shownin Fig.

1. it will thus he a -iparentthat by turning the bolt Iii-the boilv lt)may be drawn down warilly into tight. engagement upon the upper end ofthe elbow and thereby rigidly so The bo l lti is also prri the upper endof the body may be eonneet-wl to the seetion 5 of the exhaust pipe;'lhis nipple ineliules a polygonal shaped body portion having anoutwardly projecting an- I nular flange 18 form d upon oneeiiti. Thisflange is adapted for engagement against the entl of the upwardlyextending portion -16 screw of the body 20 and at the inner ed c of saidflange or annular shoulder if) is ormed to lit within this reduced end16 of the body. A coupling nut .50 is interiorly threaded as at -21 forengagement with the exterior threads on the body 10, and is formed uponone of its ends with an inwardly projecting annular flange 22, adoptedfor engagement over and upon the flange 18 on the connecting nipple 17.By threading this nut inwardly upon the upper end 16 of the body it willbe apparent that the connecting member 1.7 is securely held inconnection therewith. The body of the nipple 17 is also formed with a.reduced extcridrly threaded extension 23 for engagement with the threadsformed upon the section of themhnust pipe. In this manner it will. beobserved that the body ldmay be very easily and quickly arranged inthe'exhaust pipe of the engine. In cases where the exhaust pipe is notprovided with an elbow joint member,

it will, of course, be necessary to resort tosoiue slight modificationsin theconnecting or attaching means for the body. As such changes willbe obvious to the skilled mechanic, it will he understood that I do notdesire to be limited to the precise details of construction above setforth.

The body is interiorly formed above the tubelQ with the spacedconverging walls 24 which produce a gas passage 25. v he oppo site endsof this passage are open, one of said ends bein interiorly threaded forthe connection of t e intake pipe 26 thereto, the

body and into the nipple 7.

The carburetor proper, shown at 28, includes a cylindrical body in whichis pruvidcd a gssol-sne reservoir 29. An interior cylindrical wall 30constitutes the outer wall of the mixing chamber proper, and is formedwith a lateral extension 31 which provides ufipassugc 32 uiiordingcommunication between the mixing chamber and one end of the gas passage25 in the body 10. This extension 31 is=prorided with ears or flangesadapted to he scoured by means of suitable bolts 83 to thcciul of thebody. The body oi. the curbureter is also formed with, a dependingunnulsr boss,or extension 3 which is adopted to.bc lltt-sd with r thesplit col- .lsr 35 ormed upon the internisdistcpoi-lion of a saddleplate 38. This saddle pliit e is of semicircular form in cross sectionand is provided upon its inner face with two series of ribs 37 whichextend transversely and ininternal vs vs seat 40 is formed, upon whichthe valve disk/41 is normally and yieldingly held by a spring 42. Thisspring is arranged around the valve stem 43mm] also receives within itsupper end the reduced portion 45 of a cylindrical extension 44 formed uon the head or cup plate 46. A shoulder 4 is thus produced against whichthe upper end of the coil sprin 42 bears. The head 46 includes 0.threads portion 48 for engugement.

withthe interior threads formed upon the upper-end of the interior wall30 of the carbureting chamber. The extension" 44' is formed with alongitudinal bore 49 in which the valve stem 43 loosely fits. The heador cap member 46 is also provided with an enlarged circular disk 50which extends over and closes the upper end of gasolene reservoir 29.Upon the 'hexagonlll body 51 of the head 46 a suitable wrench ma beapplied in order to conveniently three. the extension 48 thereof intothe upper end of the mixing chamber or remove the same. Through theclosure head a series of spaced openings 52 are formed which communicatewith the carbureting chamber. Upon the head 46 a circular valve plate 53is arranged which is also provided with a series of openlugs 54. Thisvalve plate is formed with a central relatively large opening 55 thr ghwhich the shank of a bolt 56 extends. his bolt is threaded forengagement in the threaded socket or recess indicated at 57 which iscentrally formed in the head 46. Upon the bolt between the head thereofand the valve plate 53 a washer or bushing 58 is disposed.

59 designates a leaf spring also having a central opening; (30 toreceive said bolt, said spring being disposed between the head of thebolt and the bushing 58. One extremity of this leaf spring is reducedand angular-1y bent as ut (51 for engagement in u notch or recess 62formed in the periphery of the valve plate 53. The other end of saidspring is formed with a finger ling or loop 63. It will be apparent fromthis construction that the adjustable valve plate 53 provides means forregulating the supplementary supply of gal-.4

wardly projecting interiorly and exteriorly.

threaded nipples (ii. A similar nipple is also termed upon the vvall ofthe earlnireter hotly at thelower end of the gasolene reservoir 29 andextends at right angles to the first named "nipples. At each 'of thesepoints, the body of the carburcter is formed with a passage or orifice(35 which conmiunicates at: its outer end with the bore of the nipple.The inner end of the, oriticc is redueed in diameter, as indicated at66, to receive the needle point (38 of an adjustable valve rod (39, Thisrod is threaded, as at 70, for engagement with theYinterior threads uponthe nipple til. The outer end oi said rod is formed with a knurled head71. A

. nut is also threaded upon the nipple and secures one end of a leafspring 73 tightly against the wall of a earbureterill. The. free end ofthe spring bears upon theperiphery oi the knurled head 71. "he end edgeof the nipple til is dished or concaved to receive a packing gland 74. Agland nut 75 is thread ed upon the outer end of the nipple to tigi'htlycompress the packing 74 around the valve rod and a ainst the end face ofthe nipple. An open-in 7t} in the bottom wall of the gasolene reservo'ti29 atl'ords conununication between the same and one of the orilicestlfi.The reduced inner portion tit; of each orifice opens upon the valve seat40.

flhe lowenend ol' the llt)tl ol" the carhureter at one side of themixing valve and below the lateral extension 3] is formed with atransversely extending longitudinally tapering valve bore '77. With oneside of this valve hore and-adjacent theoppositcends thereof theobliquely extending passages 78 communicate. the respective passagescounect-ing said bore with he diai-nctrically opposed supply oritiees (35..

This spring: acts to yield ingly hold the valve member againstlongb tudinal shifting movement; in the bore 77 so that the ports 82 areproperly disposed for registration \vith'the passages 78 and open lugs83 when said valve member is rotated. The opposite end of-the valvemember is formed witlra suitable linger piece no whereby the same may beconveniently turned to the desired position. The end face of each of theheads 71 on the valve rod til) are provided with a circularly arrangedseries of numerals, from U to 5), whereby the approximate quantity offluid flowing through' each of theorifices 65 to the. carhuretingchamber may be ascertained by the operator. The valve rods are rotateduntil the desired numeral thereon is disposed immediately below the freeend of the leaf spring 733-. V

The disk 50 of the closure head .46 is prel'- erably provided with athreaded opening 89 located above the open end of the gasolene reservoir29. in this opening the neck of a filling funnel 90 is removablythreaded. A suitable cap or cover plate Ell is hingedly mounted as at 92upon the upperend ot' the funnel. By means of this tillingiiumiel attachment, the gasolene reservoir may be conveniently tilled.

Having now described the construction and arrangement of the severalparts oliny improved carbureter. its operation will be understood asfollows: The. reservoir 29 having been su 'zp'lied "with gasolcne andthe pipes 84' and 85 connected to a kerosene tank and a water tankrespectively. the valve 78) he valve rod (35) controlling the supply ofgasolcnc is then turncd'until the numeral (1 or 7 on the head of thevalve is below the spring 5-), thus indicating that the valve is aboutthree-fourths open. After the engine has been started on The outer endsof these.

lla)

the gasoleue as the operating fuel, the valve.

69 controlling, the kerosene supply isopened until the Indicatingnumeral"7 is -at the upper side of the valve head and the water,

control valve is also opened until the numeral 4 or 5 is uppermost.After the lapse of a short time or until the body It) is fairly hot, thevalve 79' is turned to its open posi* two so as to admit both the waterand kerosenc oil through the ports .82 and passages 78 to the orifices65 at opposite sides oi" the car- 7 bureting chamber. The supply ofgasolene is now,reduced anti the engine run on this entirely exhausted.gasolene supply requires only about eight or ten minutes after which theengine will opreduced gasolene supply until the same is he exhaustion ofthis erate "entirely upon the kerosene oil as a fuel. It will beunderstood that in the intake stroke-of the engine piston, the valve 41is drawn open by suction and the heated air drawn upwardly between theribs 37 of the saddle plate over the hot exhaust pipe and into themixing chamber proper. As this air passes into the mixing chamber, theoil and kerosene entering through the orificesmixes therewith and thewhole is then drawn into the gas passage 25 of the body 10. The flameand products of combastion from the engine exhaust striking upon thewalls of this gas passage heat the same to a very high temperature sothat the kerosene oil will be completely vaporized.

' This oil and the water, it will be understood,

is initially heated in its passage through the pipes 84 and 85 as saidpipes extend through the tube 12, which is itself highly heated by thepassage of the exhaust gases around the same. Thus, the completevaporization of the kerosene oil in its passage through the carburetorbody is assured and it is finally drawn through the intake pipe 26 andinto the explosion chamber of the engine cylinder, in proper conditionforcombustion.

The auxiliary air supply valve at the top of the-'inixer body' iscompletely closed when the engine is started. This additional air supplyis only necessary when the engine-is operating under a heavy load.

' By providing a gas passage through the carburetor body oftheparticular form illus trated in the drawings, the mixture of air,

oil, or water is held in contact with the heated walls of said passagesfor a maximum length of time so that the complete vaporization of theoil is assured, My improved cab bureter may also be very easily andquickly I arran ed in the engine exhaust pipe or remover therefrom and nview of the accessibility of the several operating parts, the device mayhe' repaired and kept in thorough working condition with but littleexpense or anual labor.

The carburetor mayfof course, be constructed in various sizes and alsoin other terms than I have indicated in th, accompanying drawings inorder to meet various;

circumstiinces or conditions which may arise in connection with the usethereof. The several cooperating parts of the mechanism may also bemodified in many minor respects and I therefore reserve the privilege ofresorting to all such legitimate alterations in the form, proportion,and arran ement of the several elements as may he airl bodied within thespirit and scope of t e'invention as claimed.
